Abstract: 1. A multilayered switching plate comprising a plurality of layers a dielectric material with electroconductive tracks on their surfaces which are switching layers and contact nodes in the form of metallized contacts aligned with each other and are electrically and mechanically connected together by an electroconductive binding material, characterized in that the contact nodes are made in the form of splices arranged between the contacts, some of them are contact pads connected with electroconductive tracks underlying switching layer, and others - aligned with them contacts - are made in the form of metallized openings shaped as truncated cone in superstratum switching layer, wherein lesser bases of the truncated cones face the contact pads of the underlying switching layer, and bigger bases of said truncated cones are connected with the electroconductive tracks on the upper side of the superstratum switching layer. 2. The multilayered switching plate of claim 1, characterized in that the contact pads are flat. 3. The multilayered switching plate of claim 1, characterized in that the bigger bases of said truncated cones, connected with the electroconductive tracks on the surface of a switching layer, are made with metallized rims along the base periphery. 4. The multilayered switching plate of claim 3, characterized in that the diameter D of the bigger base of a truncated cone, the width h of the metallized rim, the diameter d of a lesser base of a truncated cone, the thickness t of a dielectric material of a switching layer and the minimum width L of counterpart contact pad on the underlying switching layer represent the ratio: L ( or = D + 2h = d + 2t + 2h   5. The multilayered switching plate comprising a plurality of layers a dielectric material with electroconductive tracks on their surfaces which are switching layers and contact nodes in the form of metallized contacts aligned with each other and are electrically and mechanically connected together by an electroconductive binding material, characterized in that the electroconductive tracks are provided on both sides of each switching layer and are connected together within the limits of each layer by metallized junction openings, and the contact nodes consist of metallized openings in the form of truncated cones made in a superstratum switching layer, clearing metallized openings in an insulation layer, connected by an electroconductive binding material, wherein the lesser bases of truncated cones are aligned with the upper bases of the clearing metallized openings of the of the insulation layer, and the bottom bases of the clearing openings are alined with the contact pads of the underlying switching layer, connected with the electroconductive tracks on the upper side of the underlying switching layer, the upper bases of truncated cones are connected with electroconductive tracks on the upper side of the superstratum switching layer. 6. The multilayered switching plate of claim 5, characterized in that the contact pads are flat. 7. The multilayered switching plate of claim 5, characterized in that the bigger and smaller bases of truncated cones, connected with the electroconductive tracks on the surfaces of each switching layer, are made with metallized rims along the base periphery. 8. The multilayered switching plate of claim 5, characterized in that the clearing metallized openings of insulation layers are made in the form of cylinders with metallized rims along the periphery of the upper and lower bases.
